[0002] Cat litter is an object used by cat owners for their cats to bury feces and liquid food. It has good water absorption. Tofu cat litter is mainly composed of bean curd residue or plant fibers, mainly including green tea, milk fragrance, etc., and is edible. During the processing of cat litter, it is necessary to remove moisture, broken material impurities, etc. in the cat litter.
[0003] In the current cat litter separation and drying operation, most of the separation process and drying process are carried out separately. Therefore, it is necessary for workers to transfer the cat litter to the drying equipment after separation, which reduces the processing efficiency. Moreover, when the cat litter is separated, due to the presence of more moisture, it is easy to stick to the inner wall of the separation equipment, thus hindering the normal cat litter separation operation.

A plurality of heat conduction plates are fixedly connected to the outer peripheral surface of the heat conduction tube. The heat conduction plates are hollow, and the inside of the heat conduction plates communicates with the inside of the heat conduction tube. A connecting shell is fixedly connected to the side of the drying shell away from the spray heads. An exhaust port is opened on the inner wall of the connecting shell close to the drying shell, and the exhaust port communicates with the drying shell. A circulation tube is fixedly penetrated through the side of the connecting shell away from the drying shell. One end of the circulation tube away from the connecting shell is rotatably penetrated into the heat conduction tube.

Specific embodiments
[0020] The following further describes the present invention in detail with reference to the accompanying drawings.
[0021] Embodiment:
[0022] Refer to Figures 1 to 3 A tofu cat litter powder separation and dryer disclosed by the present invention includes two support plates 1. A screening cylinder 2 is fixedly connected between the two support plates 1. A collection shell 3 is fixedly connected to the side wall of one of the support plates 1 and the bottom of the screening cylinder 2. A plurality of sieve holes 4 are formed at the bottom of the screening cylinder 2, and the sieve holes 4 communicate with the collection shell 3. A drying shell 5 is fixedly connected to the side wall of one of the support plates 1 and the bottom of the screening cylinder 2. The top of the drying shell 5 communicates with the collection shell 3. The screening cylinder 2 is inclined downward toward the side of the drying shell 5. A hot air blower 6 is fixedly connected to the corresponding side wall of the support plate 1. A plurality of spray nozzles 7 are fixedly connected to the inner wall of the drying shell 5. The output end of the hot air blower 6 communicates with each of the plurality of spray nozzles 7. A preheating part 8 is arranged in the screening cylinder 2.
[0023] In this embodiment, a feed hopper is fixedly connected to the upper half of the screening cylinder 2 away from the drying shell 5. The cat litter enters the screening cylinder 2 through the feed hopper. The cat litter entering the screening cylinder 2 moves toward the drying shell 5 under the action of gravity and falls into the drying shell 5, and finally is discharged from the bottom of the drying shell 5.
[0024] The sieve holes 4 can allow the cat litter fragments and impurities to pass through, and the complete cat litter cannot pass through the sieve holes 4. When the cat litter moves toward the drying shell 5 in the screening cylinder 2, the fragments and impurities pass through the sieve holes 4 and fall into the collection shell 3, and only the complete cat litter will enter the drying shell 5.
[0025] When the hot air blower 6 works, it outputs hot air, and the hot air is sprayed onto the cat litter in the drying shell 5 through the spray nozzles 7 to dry the cat litter.
[0026] Further, a number of guide plates 9 are fixedly connected inside the drying shell 5. The guide plates 9 are inclined, and the inclination directions of two adjacent guide plates 9 are opposite. After the cat litter enters the drying shell 5, it will fall onto the corresponding guide plate 9, then slide on this guide plate 9, and then fall onto another guide plate 9 below until it contacts all the guide plates 9 before being discharged from the bottom of the drying shell 5. The arrangement of the guide plates 9 increases the movement time of the cat litter inside the drying shell 5, enabling the cat litter to fully contact the hot air, thereby improving the drying effect of the cat litter.
[0027] In a further preferred embodiment of the present utility model, as Figure 2 shown, the preheating part 8 includes a heat conduction tube 81 rotatably connected inside the screening cylinder 2. A number of heat conduction plates 82 are fixedly connected to the outer peripheral surface of the heat conduction tube 81. The heat conduction plates 82 are hollow, and the inside of the heat conduction plates 82 communicates with the inside of the heat conduction tube 81. A communicating shell 83 is fixedly connected to one side of the drying shell 5 away from the nozzle 7. An exhaust port 85 is opened on the inner wall of the communicating shell 83 close to the drying shell 5, and the exhaust port 85 communicates with the drying shell 5. A circulation tube 84 is fixedly penetrated through one side of the communicating shell 83 away from the drying shell 5. One end of the circulation tube 84 away from the communicating shell 83 is rotatably penetrated inside the heat conduction tube 81. One end of the heat conduction tube 81 away from the circulation tube 84 is connected to the input end of the hot air blower 6 through a communicating part 86.
[0028] In this embodiment, both the heat conduction tube 81 and the heat conduction plates 82 are made of copper material, and the heat conduction effect is better. The cat litter cannot pass through the exhaust port 85. When the hot air blower 6 is working, the input end of the hot air blower 6 sucks the gas inside the heat conduction tube 81 through the communicating part 86. Since the heat conduction tube 81 communicates with the circulation tube 84, the circulation tube 84 communicates with the communicating shell 83, and the communicating shell 83 communicates with the drying shell 5 through the exhaust port 85, the hot air passing through the cat litter is sucked by the input end of the hot air blower 6 during operation. The hot air sequentially passes through the exhaust port 85, the communicating shell 83, the circulation tube 84, the heat conduction tube 81, and the communicating part 86 and then returns to the hot air blower 6. When the hot air moves inside the heat conduction tube 81, it will increase the temperature of the heat conduction tube 81 and the heat conduction plates 82. The heat conduction tube 81 and the heat conduction plates 82 exchange heat with the cat litter inside the screening cylinder 2, so that the cat litter inside the screening cylinder 2 is preheated, reducing the moisture on its surface, thereby preventing the cat litter inside the screening cylinder 2 from adhering to the inner wall of the screening cylinder 2.
[0029] In a further preferred embodiment of the present utility model, as Figure 2 shown, the communicating part 86 includes a side shell 861 fixedly connected to the side wall of the corresponding support plate 1. The heat conduction tube 81 extends into the side shell 861, and an impeller 862 is fixedly sleeved on the outer peripheral surface of the heat conduction tube 81 inside the side shell 861. A communicating pipe 863 is rotatably penetrated through the heat conduction tube 81 away from the circulation tube 84. The communicating pipe 863 is fixedly penetrated through the side shell 861, and one end of the communicating pipe 863 away from the heat conduction tube 81 extends to the upper half inside the side shell 861. The input end of the hot air blower 6 communicates with the lower half of the side shell 861.
[0030] In this embodiment, since the connecting pipe 863 and the flow pipe 84 are rotatably inserted through both ends of the heat conduction pipe 81 respectively, the connecting pipe 863 and the flow pipe 84 are both communicated with the heat conduction pipe 81, and the heat conduction pipe 81 can rotate freely. When the hot air blower 6 works, it sucks air, and the air flow enters the connecting pipe 863 through the heat conduction pipe 81, and then is discharged from one end of the connecting pipe 863 away from the heat conduction pipe 81. The air flow impacts the impeller 862, driving the impeller 862 to rotate. The impeller 862 drives the heat conduction rod and the heat conduction plate 82 to rotate. The heat conduction plate 82 pushes the cat litter in the screening cylinder 2, which not only makes the high-temperature heat conduction plate 82 fully contact the cat litter to improve its preheating effect, but also can push the cat litter to move in the screening cylinder 2, thereby improving the effect of the broken materials and impurities in the cat litter passing through the sieve holes 4, and further improving the cat litter separation effect. The air flow passing through the impeller 862 enters the input end of the hot air blower 6 and is ejected from the nozzle 7 of the hot air blower 6 after being driven by the hot air blower 6 to dry the cat litter in the drying shell 5.
[0031] The hot air blower 6 is selected as a high-power model to ensure that the air flow during its operation is sufficient to drive the impeller 862 to rotate.
[0032] In a further preferred embodiment of the present utility model, as Figure 2 shown, a water absorption layer 10 is fixedly connected inside the connecting shell 83, and one end of the flow pipe 84 extending into the connecting shell 83 is located on the side of the water absorption layer 10 away from the drying shell 5.
[0033] In this embodiment, the water absorption layer 10 is made of water absorption resin material. After the hot air ejected from the nozzle 7 passes through the cat litter, it enters the connecting shell 83 through the exhaust port 85, and then enters the flow pipe 84 only after passing through the water absorption layer 10. The water absorption layer 10 adsorbs the water vapor in the hot air to prevent the water vapor from being ejected from the nozzle 7 after circulation and having an adverse effect on the drying of the cat litter.
[0034] In a further preferred embodiment of the present utility model, as Figure 2 shown, the inner bottom wall of the collection shell 3 is inclined downward toward the side away from the drying shell 5, and a discharge port 11 is opened at the side wall of the corresponding support plate 1 corresponding to the collection shell 3.
[0035] In this embodiment, the broken materials and impurities falling into the collection shell 3 slide along the inner bottom wall of the collection shell 3 and are discharged from the collection shell 3 through the discharge port 11, which is convenient for the staff to collect the broken materials and impurities.
[0036] The implementation principle of the above embodiment is:
[0037] During the processing of cat litter, the hot air blower 6 is started. The operation of the hot air blower 6 causes the nozzle 7 to discharge hot air. The hot air passes through the drying shell 5 and then enters the heat conduction pipes 81 and the heat conduction plate 82, causing the heat conduction plate 82 and the heat conduction rod to heat up. Then the hot air impacts the impeller 862, driving the heat conduction plate 82 and the heat conduction rod to rotate. Finally, the hot air returns to the hot air blower 6.
[0038] Cat litter is added into the screening cylinder 2 through the feed hopper. The broken materials and impurities in the cat litter pass through the sieve holes 4 and fall into the collection shell 3. The complete cat litter moves towards the drying shell 5 under the action of gravity and drops into the drying shell 5. The cat litter contacts the high-temperature heat conduction plate 82 in the screening cylinder 2 and is preheated, reducing the moisture on its surface. Moreover, the heat conduction plate 82 pushes the cat litter to move, enabling the broken materials and impurities in the cat litter to fully pass through the sieve holes 4. The cat litter that drops into the drying shell 5 is directly dried by the hot air ejected from the nozzle 7, and the dried cat litter is discharged from the bottom of the drying shell 5.
[0039] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
